Couple of questions about scenes and renders

Is carrara capable of making hi-definition images that can be used in Poser for backgrounds?  If so, how about equirectangular style images for use in an Env Sphere?

Also, is it OK to offere for freebie, a preset scene that you make in Carrara, if you do not give any of the assets (if that is possible)?

If so, has anyone made a beach scene?

Thanks!

Use a sphere cam and set your output render to a ratio of 2:1. Like 4000x2000 or even higher.

I don’t under stand the question. Are you talking about giving away a Carrara scene or a rendered background?

There are a few beach scenes in the native content I believe…

Yea, sorry, giving away a Carrara scene file that is already made.  So for example, if I made a nice mountain or beach or other scene using Carrara assets, saving the scene, and giving away the scene file as a freebie. (i.e. they need Carrara to load it)

(ill try the sphere cam here, and see how it works, thanks)

If you are not using anyone else’s models or textures…., just using Carrara tools like terrain, plants, skies, or your own models/textures then you can give away the whole scene as a freebie. There use to be a Carrara Freebies forum…. You can also check ShareCG to see what Carrara freebies are usually given away….

OK, so those Spreical images come out a little distorted on an Env Sphere…?  Is that for a Dome or a Sphere?

(unless my Zoom and distance to near plane settings are wrong…not sure about those)

Compare attached carrara photo to this photo:  Equirectangular beach

The linked one has two swells, versus the single lump, if you will

Without knowing the available options (haven’t touched Carrara in a very long time…and never did get that far into it), I’d say it’s likely, just by looking at the way it’s distorting.

It just means it’s expensive.

It looks to me that your spherical camera is not quite horizontal.  Check the “motion” parameters tab and make sure that your camera points to the horizon with an X rotation of 90 degrees exactly and zero for the other two rotations (or is it -90 - one or the other!) and see if that works.

The OP keeps asking about equirectangular. Not sure if Carrara does that. I know it does spherical renders, as I’ve done a couple myself for backgrounds.

I find it somewhat liberating not to be encumbered by accuracy.

For the Spherical renders, what did you apply them to?  I am trying to apply them to the inside of a large sphere (Bagginsbill’s Environment Sphere to be exact).  Then I make the ground plane a shadow catcher and ta-da!

Anyway, here is where his Sphere is at, but it call for Equirectangular…which seems to be different than the “spherical” that Carrara is producing.

Ugh! Sounds overly complicated and maybe unnecessary. You can create a sphere primitive or create a vertex sphere and use that for your image map/shader, and then scale the sphere to whatever size you want. If you want IBL lighting, like an HDRI, then you can put an image, HDRI, color, color gradient, etc. in Carrara’s Scene background, and it will wrap it around the virtual universe, then turn on Skylight under GI in the render room and done.


Here’s a spherical render I made in Carrara 7.2 Pro. It uses Dystopia City Blocks and some customized shaders. Try it in the scene’s background. For extra fun, use it as an IBL by turning Skylight on. I also have a daylight version with a sucky mountain in the background.

Yea, see those 2 spherical renders you made there are correct.  I am not getting the same?

Other than an OBJ boat in there, its all Carrara 7.2 pro.  I got a background sky map

Here is the basic setup I have.

...and here is the render.  Its nothing like the spherical type you have there in your sharecg stuff.  I must be missing something.  ????

OK, I may have found the problem.  My focal length on my camera was set to like 75, and it should have been around 15mm or so.  This may be workin.

The trick to this is to place your spherecam at the same height as the camera in the other scene. That way their “eyes” match and the ground planes will line up.

If you are making a 360 for viewing (as if through the character’s eyes) then the camera should be at about 5 ft high (or a little less seems to be the average tv show camera height…).

The results of this render, the 2:1 image you have posted is called Equirectangular. This image is ready to wrap onto a sphere. In Carrara you can load it as the Background.

OK, I’ll try that on the next one.  I just switched to a large non-spherical render and dropped it in as a background via postwork instead, since I could not get it to work properly.  (result)

Thanks for the tip!
